To all whom it may concern:

Be it known that 1, ROBERT M. MILLER, a citizen of the United States, residing at Montgomery, in the county of Lycoming and State of Pennsylvania, have invented a new and useful Extension-Table, of which the following is a specification.

This invention relates to extension tables, and has for its object to provide such a table with a two part central pedestal and a centrally divided top connected together by the usual slides which permit the table to be increased in length by drawing out the parts. To this end a board is bolted on the top of each half pedestal with a plate fastened on each end of each board which plate supports one of said slides. Each half top is screwed to two slides having independent movement on the pedestal slides. A locking means is provided for holding the two half pedestals together and separate locking means are employed for preventing the separation of the table top. Means are also provided whereby the lower ends of the pedestal are brought into contact and held so when the table is closed.

With these and other objects in view the invention consists of the novel construction and arrangement of parts hereinafter described and claimed and illustrated in the accompanying drawing in which Figure 1 is a bottom plan view of a part of an extension table top with the supports removed. Fig. 2 a plan view of the table top supports with the table top removed. Fig. 3 a sectional view through the complete table on the line 3-3, Figs. 1 and 2, and Fig. 4 a sectional detail view on the line 4-4 of Fig. 2. Fig. 5 is a perspective view of a ribbed plate forming partof the table structure.

Like reference characters are used for the same parts in all the figures.

The pedestal A of the table is divided vertically into two equal halves 1 and 2, on the top of each of which halves is bolted a horizontally disposed board 3 and 4 re spectively, the board 4 being longer than the board 3 and parallel with it. On each end of each board is screwed or otherwise fastened a flat metal plate 5 having a conveXly curved central rib 6 extending across said plate in line with the rib of the plate 5 on the opposite end of the board to which it is fastened. A notch 7 is cut across the center of each rib exposing the board below through which a hole 8 is bored for the fastening bolt by means of which the top of the table is fastened to the pedestal.

The top B of the table is divided centrally into two parts 9 and 10 supported on each side of the center by four slides 11, 12, 13 and 14, disposed at right angles to the division line between the two parts of the top as usual. The outer slides 11 are fastened to the half top 9 while the innermost slides 14 are screwed to the other half top 10. Between the slides 11 and 14 are the other slides 12 and 13 connected to the slides 11 and 14 by grooves and tenons in the usual way, but these slides 12 and13 are not otherwise connected to the table top. Bolted or screwed to each middle slide 12 and 13 is a plate 15 having a central boss 16 depending therefrom in which is made a hole for a bolt 17 to pass therethrough. The plates l5 are so situated that when the table top is correctly placed on the pedestal, the bolts 17 will pass through the notches 7 of the ribs 6 and the holes 8 in the boards 3 and 4 and project below the latter where they will be fastened by nuts 18 as shown in Fig. 3. Cushions 19 in the form of rubber buttons are secured to the inner ends of the plates 15 on which cushions the corresponding ends of the plates 5 rest while the other ends of the plates 15 bear on the ends of thumb screws 20 which pass upwardly through the boards 3 and 4 and are threaded in the plates 5.

A spring latch 21 having a perforation 22 is fastened to one of the boards 3 or 4, and a keeper 23 provided with an upwardly projecting pin 24 is screwed to the other board thus constituting a locking device. lVhen the half pedestals are in contact the spring latch is in engagement with its keeper-pin 24 and the boards 3 and 4 and the upper ends of the half pedestals are prevented from separating. The table top is also provided with fastening means to hold the two parts thereof from being pulled apart as clearly shown in Fig. 1, where will be seen a spring plate 25 fastened to one half top with a whole made in the free end that projects beyond the diametric edge of said half top. A disengaging rod 26 slidable in a sheath 27 attached to the other half top, has an operating finger 28 near the outer side of the table for rotating and longitudinally moving the rod and detaching the spring latch or plate 25 from its connecting the slides keeper, the said keeper being the corresponding end of the rod 26. A stop 29 limits the outward movement of the disengaging rod 26.

A table constructed as above described may be lengthened by operating the rod 26 to disengage the spring latch 25 and then drawing apart the two half tops, the ped estal remaining undisturbed. Should a greater length of table be desired the spring latch 21 must be raised and the top sections again drawn apart, this time separating the half pedestals until the limit of length is reached.

The table is reduced to its initial length merely by pushing the parts together, the latches'fastening automatically. If the two parts of the pedestal at the bottom when the table is closed, they may be brought into close contact by means of the thumb screws 20 which on being direction press against, the plates 15 and depress the outer edges 4 downwardly, rockingi turned in the right of the boards 3 and them on the ribs 6 and forcing the bottom end of the half pedestals together.

What is claimed is 1. An extension table having a vertically divided central pedestal, a board bolted to the top of each pedestal part, a rib at each end of each of said boards, a divided top, slides fastened thereto to enable the top to be drawn apart, slides disconnected from the table top movable longitudinally between the table top slides, tened to each of said independent slides adapted to rest on said ribs, said lugs entering each a notch in each of said ribs, bolts to said boards passing through said plates and ribs to permit said pedestal parts to oscillate, and independent means for connecting and said divided top.

2. An extension table having a two part pedestal vertically divided, a board on each half pedestal, said boards being in parallel relation and one of said boards being longer than the other, a plate fastened to each end of each board and having a convex rib do not come together a plate having a lug fassaid pedestal parts 1 tals and connections extending through the perfosaid slides thereon parallel with the ribs on the other board, a divided table top, and outer and intermediate slides carried by the top between said boards and said top, the outer slides being connected to respective sections of the table top and the intermediate slides being attached each to one end of each board with the convex rib interposed.

3. An extension table having a two part central pedestal, a divided top supported on said pedestal by intervening slides, connections between certain slides and each half of the said table top, plates with convex ribs on each part of said pedestal between the same and the remaining slides, connections between the last named slides and the pedestals extending through the ribs, and means carried by the plates for rocking the pedestal and limiting the rocking movement.

4. An extension table having a two part central pedestal vertically divided, a divided top supported on said pedestal by slides, plates carried by the pedestal and each provided with a convex rib having a central perforation, certain of the slides resting 011 the ribs, and connections between the pedes the slides resting on the ribs, said rations in the ribs.

5. An extension table having a two part central pedestal vertically divided, a divided top supported on said pedestal by slides, plates carried by the pedestal and each provided with a transverse rib parallel with the line of division of the pedestal and having a central perforation, connections between and the pedestal, said connections extending through the perforations in the ribs, a yielding member between one end of each plate and the corresponding slide, and an adjusting screw between the other end of the plate and the corresponding slide.

In testimony that I claim the foregoing as my own, I have hereto. afiixed my signature in the presence of two witnesses.

ROBERT M. MILLER.
